The 2SK2035 transistor is the subject of this 295 KB PDF, most likely the manufacturer datasheet given that 2SK is the JIS prefix for N-channel FETs.

A 291 KB PDF dedicated to the 2SK1830. The 2SK code is the Japanese JIS designation for N-channel field-effect transistors, so this is almost certainly a datasheet…

PDF of about 295 KB for the 2SK1827. In JIS part numbering, 2SK stands for an N-channel FET, so the content should be a datasheet rather than a board-level drawing.

Datasheet document for the 2SK1103 transistor, filed as a 29.5 KB PDF. Parts beginning with 2SK are N-channel field-effect transistors registered under the JIS scheme…

A 29.4 KB PDF for the 2SJ569LS, catalogued as a schematic though it is named in the style of a component datasheet.

Indexed as a schematic, this 296 KB PDF is named only 2SC5094, a JIS-style transistor designation where 2SC stands for an NPN device rated for high-frequency operation.

A 296 KB PDF identified only by the JEDEC-style part code 2N5769. The catalogue lists it as a schematic, yet the name points to a single discrete semiconductor, so its…

A 292 KB PDF datasheet for the 2N2369, with an extra RE suffix in the file name whose meaning is not stated, catalogued as a schematic.

A 293 KB PDF filed under schematics and titled 28F001, which belongs to the 28F flash memory family, usually a 1 Mbit boot block device.
